Answer
\( a + (-b) = 2 \)
Solution
To evaluate \( a + (-b) \) where \( a = 4 \) and \( b = 2 \), we first need to find \( -b \).
Given:
\[
b = 2
\]
Thus,
\[
-b = -2
\]
Now we can substitute \( a \) and \( -b \) into the expression:
\[
a + (-b) = 4 + (-2)
\]
Now, we perform the addition:
\[
4 + (-2) = 4 - 2 = 2
\]
Therefore, the value of \( a + (-b) \) is:
\[
\boxed{2}
\]
